Since you give no credence to the great response in this post above,
http://www.baptistboard.com/showpost.php?p=1707552&postcount=6, I will offer a few direct Scriptures to refute your erroneous position. Below are DIRECT references to the universal church. I will next also show some indirect references:
Matt 16:17-18 And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it.
Acts 2:47 praising God and having favor with all the people. And the Lord added to the church daily those who were being saved.
Acts 9:31 So the church throughout all Judea and Galilee and Samaria had peace and was being built up. And walking in the fear of the Lord and in the comfort of the Holy Spirit, it multiplied.
1 Corinthians 12:28 And God has appointed in the church first apostles, second prophets, third teachers, then miracles, then gifts of healing, helping, administrating, and various kinds of tongues.
1 Corinthians 15:9 For I am the least of the apostles, unworthy to be called an apostle, because I persecuted the church of God.
Ephesians 1:22–23 And he put all things under his feet and gave him as head over all things to the church, which is his body, the fullness of him who fills all in all.
Ephesians 5:25–27 Husbands, love your wives, as Christ loved the church and gave himself up for her, that he might sanctify her, having cleansed her by the washing of water with the word, so that he might present the church to himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish.
Colossians 1:18 And he is the head of the body, the church. He is the beginning, the firstborn from the dead, that in everything he might be preeminent.
Hebrews 12:23 to the general assembly and church of the firstborn who are registered in heaven, to God the Judge of all, to the spirits of just men made perfect,
Indirect references to the church universal:
John 15:2 Every branch in me that does not bear fruit he takes away, and every branch that does bear fruit he prunes, that it may bear more fruit. ...
John 15:6 If anyone does not abide in me he is thrown away like a branch and withers; and the branches are gathered, thrown into the fire, and burned.
Romans 11:19–22 You will say then, “Branches were broken off that I might be grafted in.” Well said. Because of unbelief they were broken off, and you stand by faith. Do not be haughty, but fear. For if God did not spare the natural branches, He may not spare you either. Therefore consider the goodness and severity of God: on those who fell, severity; but toward you, goodness, if you continue in His goodness. Otherwise you also will be cut off.
Romans 14:10-11 Why do you pass judgment on your brother? Or you, why do you despise your brother? For we will all stand before the judgment seat of God; for it is written, “As I live, says the Lord, every knee shall bow to me,
and every tongue shall confess to God.”
Ephesians 2:19–22 19 So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone, in whom the whole structure, being joined together, grows into a holy temple in the Lord. In him you also are being built together into a dwelling place for God by the Spirit.
Ephesians 4:4 There is one body and one Spirit, just as you were called in one hope of your calling...
Ephesians 5:23 For the husband is head of the wife, as also Christ is head of the church; and He is the Savior of the body.
2 Timothy 2:19 Nevertheless the solid foundation of God stands, having this seal: “The Lord knows those who are His,” and, “Let everyone who names the name of Christ depart from iniquity.”
Hebrews 12:22–24 But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect, and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.
1 Peter 2:5 you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ.
Revelation 5:9-10 And they sang a new song, saying, “Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation, and you have made them a kingdom and priests to our God, and they shall reign on the earth.”
Revelation 14:6-7 Then I saw another angel flying directly overhead, with an eternal gospel to proclaim to those who dwell on earth, to every nation and tribe and language and people. And he said with a loud voice, “Fear God and give him glory, because the hour of his judgment has come, and worship him who made heaven and earth, the sea and the springs of water.”
Revelation 14:12-13 Here is a call for the endurance of the saints, those who keep the commandments of God and their faith in Jesus. And I heard a voice from heaven saying, “Write this: Blessed are the dead who die in the Lord from now on.” “Blessed indeed,” says the Spirit, “that they may rest from their labors, for their deeds follow them!”
Revelation 15:3-4 And they sing the song of Moses, the servant of God, and the song of the Lamb, saying, “Great and amazing are your deeds, O Lord God the Almighty! Just and true are your ways, O King of the nations! Who will not fear, O Lord, and glorify your name? For you alone are holy. All nations will come and worship you, for your righteous acts have been revealed.”
Revelation 19:6-9 Then I heard what seemed to be the voice of a great multitude, like the roar of many waters and like the sound of mighty peals of thunder, crying out, “Hallelujah! For the Lord our God the Almighty reigns. Let us rejoice and exult and give him the glory, for the marriage of the Lamb has come, and his Bride has made herself ready; it was granted her to clothe herself with fine linen, bright and pure”— for the fine linen is the righteous deeds of the saints. And the angel said to me, “Write this: Blessed are those who are invited to the marriage supper of the Lamb.” And he said to me, “These are the true words of God.”
Of course, you may choose to ignore all these very clear Scriptures, that is your business, but I take heed to them, wanting to be one of the ones standing before the throne of God with the multitudes that make up the church that Jesus Christ said that He would build. Those who radically separate themselves from all of God's people may find themselves separated eventually and eternally...
